PYROID® Pyrolytic Graphite Product Line

Vitreous Carbon Substrate
Our PYROID® pyrolytic graphite is a very light weight, 5’9’s pure, solid crystal composition, with no granular components, extremely smooth surface, capable of withstanding cryogenic temperatures as well as temperatures in excess of 3,000°C
The material is extremely anisotropic, meaning it conducts heat and electricity in the a-b plane like copper but acts like a ceramic in the normal direction. In an annealed state, the thermal and conduction properties increase up to four to eight times that of aluminum and copper respectively.
The material has zero porosity making it extremely stable and exhibits no outgassing. It is ideal for use in corrosive environments including acids and chlorine, and is highly transparent to organic samples and electrons, for analytical work, such as x-ray investigation, metallurgical, crystal growth, medical imaging technology etc.

Pyrolytic Graphite Stripper Film

Smooth pyrolytic graphite stripper film is used in radiation sources, nuclear particle high energy density research, and medical diagnostic imaging instruments Pyrolytic graphite film offers major customer benefits relative to alternative materials such as amorphous carbon film or polycrystalline graphite films.

Pyrolytic graphite film is:
– Stable at high temperature and vacuum
– Easy to flex due to inherent higher flexural modulus
– Erodes very slowly

Resulting in:
– Higher strength than alternative materials
– Last 5 times longer than alternative materials
